Research on animal learning and cognition has so far mainly focused on a few prominent model species, including primates, corvids and dogs. For years, comparative psychologists and ethologists have been suggesting that more animal species should be considered in comparative cognitive science. The abundance and accessibility of livestock offer an opportunity, not merely to extend the comparative approach, but also to deepen our knowledge of the mental lives of farm animals. Such approaches also help to assess the needs of farm animals, in order to improve their welfare. In recent years, scientific interest in different aspects of farm animal psychology, including emotionality, personality and cognitive capacities, has been on the rise, proving that farm animals have sophisticated cognitive skills to comprehend and cope with their environment. As knowledge of how farm animals perceive and interact with their physical and social environments is crucial for animal welfare, the aim of this Research Topic is to promote investigations of farm animal cognitive capacities and their implications for animal welfare-related issues. We have therefore collected original research and review articles, as well as opinion and perspective papers that are distributed among the two hosting magazines, Frontiers in Veterinary Science (section Animal Behavior and Welfare) and Frontiers in Psychology (section Comparative Psychology). The published articles present state-of-the-art research on farm animal learning and cognition, highlight future perspectives in this research area and pinpoint shortcomings and limitations in interpreting current findings. They offer new cross-disciplinary frameworks (e.g. links between affective states and cognition) and discuss the applied implementation of these findings (e.g. cognitive enrichment). These contributions will increase our understanding of the cognitive mechanisms that enable farm animals to effectively interact with their environment and pave the way for future cross-disciplinary endeavors.
The Spanish empire in the Americas spanned two continents and a vast diversity of peoples and landscapes. Yet intriguing parallels characterized conquest, colonization, and indigenous resistance along its northern and southern frontiers, from the role played by Jesuit missions in the subjugation of native peoples to the emergence of livestock industries, with their attendant cowboys and gauchos and threats of Indian raids. In this book, nine historians, three anthropologists, and one sociologist compare and contrast these fringes of New Spain between 1500 and 1880, showing that in each region the frontier represented contested ground where different cultures and polities clashed in ways heretofore little understood. The contributors reveal similarities in Indian-white relations, military policy, economic development, and social structure; and they show differences in instances such as the emergence of a major urban center in the south and the activities of rival powers. The authors also show how ecological and historical differences between the northern and southern frontiers produced intellectual differences as well. In North America, the frontier came to be viewed as a land of opportunity and a crucible of democracy; in the south, it was considered a spawning ground of barbarism and despotism. By exploring issues of ethnicity and gender as well as the different facets of indigenous resistance, both violent and nonviolent, these essays point up both the vitality and the volatility of the frontier as a place where power was constantly being contested and negotiated.
This book comparatively examines the etiopathogenetic, clinical-pathological, diagnostic and therapeutic strategies of the main bone tumors of domestic animals. The book also includes a description of the most significant aspects of macroscopic, microscopic, immunohistochemical, instrumental, diagnostic imaging and molecular biology aspects of spontaneous bone tumors in Veterinary Medicine, with also interspecies comparative aspects, including the human one. Last but not least, the book provides an overview of the new diagnostic and therapeutic frontiers related to the approach to animal bone tumors. The book serves as essential reading for professionals, researchers and students who work or want to tackle three paths in the field of comparative veterinary bone oncology.
Historians of the American West, perhaps inspired by NAFTA and Internet communication, are expanding their intellectual horizons across borders north and south. This collection of essays functions as a how-to guide to comparative frontier research in the Americas. Frontiers specialist Richard W. Slatta presents topics, techniques, and methods that will intrigue social science professionals and western history buffs alike as he explores the frontiers of North and South America from Spanish colonial days into the twentieth century. The always popular cowboy is joined by the fascinating gaucho, llanero, vaquero, and charro as Slatta compares their work techniques, roundups, songs, tack, lingo, equestrian culture, and vices. We visit saloons and pulperias as well as plains and pampas, and Slatta expertly compares clothing, weather, terrain, diets, alcoholic beverages, card games, and military tactics. From primary records we learn how Europeans, Native Americans, and African Americans became the ranch hands, cowmen, and buckaroos of the Americas, and why their dependence on the ranch cattle industry kept them bachelors and landless peons.
Scientific experiments using animals have contributed significantly to the improvement of human health. Animal experiments were crucial to the conquest of polio, for example, and they will undoubtedly be one of the keystones in AIDS research. However, some persons believe that the cost to the animals is often high. Authored by a committee of experts from various fields, this book discusses the benefits that have resulted from animal research, the scope of animal research today, the concerns of advocates of animal welfare, and the prospects for finding alternatives to animal use. The authors conclude with specific recommendations for more consistent government action.
